laro;e pine tree on tlie side of the track. I have also observed large 

 flocks at Eglington, Out., this winter. 



18. Field Mouse impaled by Lanius borealis.— It on and Field 

 Mouse {Arvicola ripariusT) impaled on a thorn by the Butcher Bird 

 in some small thorn bushes in Eosedale, on January 27th, but did not see 

 the butcher. — James H. Ames. 



19. Aquila chrysaetos. — The Golden Eagle is represented in my 

 store by the immense wings and claws of a specimen that was killed 

 in Muskoka, August, 1889. 



20. Haliaetos leucocephalus. — A male Bald Eagle was shot a little 

 west of Kingston, Ont., in August, 1889, and sent to me. 



21. Syrnium nebulosum. — Six years ago the Barred Owl came in 

 numbers, since then it has been hard to obtain a specimen till this 

 season, during which about a dozen have been brought to m}'- store. 

 The largest and finest was a female that was shot on the R. C. Arch- 

 bishop's Palace on Sherbourne Street. It measured : — Ig. 20J ; wg. 13 ; 

 tl. 9| inches. 



22. Ulula cinerea. — The Great Grey Owl has this year been very 

 common in Ontario. During the last thirteen years I have handled 

 five or six specimens in my business as taxidermist, and have heard 

 of but a few other Ontarian specimens. But this winter (1889-90) I have 

 received twenty-three specimens, and have had them reported from 

 various parts of the Province. One of my acquaintances stationed at 

 Barrie received twenty-six this season. They began to come into this 

 region in November, and increased in numbers up to February, after 

 which they became very scarce again. Mr. Thompson suggests 

 that the unprecedented fall of snow in the North-west may account 

 for this unusual migration of owls, as it would effectually conceal the 

 swarming Arvicolcc of the boreal regions, and thereby rob the owls of 

 a staple article of diet and compel them to migrate. 



23. Nyctala tengmalmi richardsoni. — Tlie Richardson's Owl is 

 equally rare in all seasons here. I never receive more than three or 

 four in a year, sometimes none at all. They are usually taken in the 

 fall, but occasionally in the early spring time. 



24. Nyctala acadica. — The Saw-whet is our smallest species, much 

 like richardsoni on a small scale. It is always scarce; this season even more 

 so than usual. In the fall of 1889 they appeared in great numbers 

 on Toronto Island. One man assured me that he collected over twenty-
